Jianguo Jiang · Modern Electronics Technique · 2008
An analysis of temperature-resistance computation algorithm of Pt100 platinum resistor is discussed.Based on the comparison of the Dichotomy method,programming structure,computing complexity,absolute accuracy and relative operating speed of the Newton method are analyzed in detail.Results show that,at the same accuracy constraint,the Newton method has smaller computation complexity,higher accuracy,lower calculation error and faster operation speed than the Dichotomy method.Therefore,the Newton method is a appropriate algorithm for the temperature computation of Pt100 platinum resistor.
